[Linux-HA] Problem to start hbagent

Tue Jul 8 03:43:29 MDT 2008

I installed the 2.0.6 version with the patch to enables snmp_subagent to work without CRM.
I've no more problems to start hbagent, now :-).

But after configuring snmpd: I get the following error when I start snmpwalk:

rot# snmpwalk -v2c localhost -c public LinuxHA

LINUX-HA-MIB::LinuxHA = No more variables left in this MIB View (It is past the end of the MIB tree)

Do you know what this error means?

Maybe somethink wrong in snmpd configuration?

I added these lines in snmpd.conf:

# create a SNMPv1/SNMPv2 community

rwcommunity  public

# this makes the snmpd a master snmp agent, which can

# support AgentX subagents.

master agentx

# this defines your localhost as the trapsink.  so traps

# or rather the SNMPv2 informs, will be sent to localhost.

trap2sink localhost

I restarted snmpd service and I can see agentx with netstat command:

netstat -nlp --protocol unix

Hello,

I've tried to modify linux-ha hbagent.c to disable v2 functions access. But I still can't access to the MIB by snmpwalk...

I think I have only two issues: 

- upgrade to linux-ha v2 style 

- or used heartbeat old linux-ha version

Did someone test the patch described here (http://lists.community.tummy.com/pipermail/linux-ha-dev/2006-July/013261.html): it enables snmp_subagent to work without CRM, ... but it can only be applied on 2.0.6 version...

Thank you for your responses ... or any other suggestions.

Anne

It is exactly my problem... I would like to know if there is a way to compile snmp-subagent to allow hbagent to connect to heartbeat v1 (when option crm is set to off). I tried the option --enable-crm=no, but I have errors when hbagent is compiled in that way.

There is however two programs hbagent.c and hbagentv2.c in source package...

Maybe I should ask in linux-ha-dev mailing list?

I believe Lienard was referring to Heartbeat v1, not SNMP v1.

While I don't have the answer, his problem was that starting up hbagent in his v1-style cluster fails because it tries to connect to the CIB and since it's a v1 haresources cluster, it obviously can't connect to the non-existent CIB and dies instead.
